Abstract:The SuperKEKB accelerator is an electron-positron collider, and its final beam focusing system consists of 55 superconducting magnets. To improve beam collision performance, KEK is studying upgraded final focus quadrupole magnets using Nb3Sn technology in collaboration with FNAL and Furukawa Electric. In this presentation, we will report on the need for the magnet upgrade and the current project status.
